CROSS REFERENCE TO RELATED APPLICATIONS

The present application is related to Community Plant Variety application 2012/2344, filed in the Community Plant Variety Office on Oct. 25, 2012, the entire contents of which are hereby incorporated by reference.

BACKGROUND OF THE INVENTION Discussion of the Background

The new and distinct grapevine described and claimed herein originated from a hand pollinated cross of Malvasia (Bianca) di Candia Aromatica (pollen parent) and Moscato Ottonel (seed parent), neither of which are protected by plant patent, plant variety protection certificate, or similar. The seeds were subsequently germinated and the resulting plants were planted in the field. The present variety of grapevine was selected as a single plant, and asexually propagated by hardwood cuttings. The resulting propagules were planted and were found to reproduce true-to-type through at least three generations of asexual reproduction, with the observations taking place from 2004 to 2010 in San Michele All'Adige(TN)—Trentino Alto Adige—Italy (46° 11′ Lat. N, 11° 28′ Long. E, 235 s.l.m.).

SUMMARY OF THE INVENTION

To the inventor's knowledge, there are no varieties similar to the new variety; being a crossing result, they contain 50% of the genetic material of the seed parent and 50% of the genetic material of the pollen parent.

The present variety produces white berries in the parents. The present variety matures 1 week earlier than the parents, and is much less sensitive to Botrytis cinerea compared to the parents. The present variety berries exhibit a loose bunch and have the presence of both geraniol and linalool.

The variety IASMA ECO 3 has no anthocyanin pigmentation of tips, while in Muscat Ottonel variety the anthocyanin pigmentation is very strong and widespread and in Malvasia di Candia variety is weak and piping.

The shoot on blooming is horizontal in Muscat Ottonel variety, semi erect in Malvasia di Candia variety and in the variety IASMA ECO 3.

The dorsal and ventral shoot on Blooming in Muscat Ottonel variety and Malvasia di Candia variety, in internodes and nodes, is green (150A) with red (44B) strips, while it is green (150A) in the variety IASMA ECO 3.

The variety IASMA ECO 3 tendrils are long, like those of Malvasia di Candia variety, while in Muscat Ottonel variety they are medium.

The Young leaf of the variety IASMA ECO 3 is bronze (N25A), becoming green (149B), while that of Malvasia is green (150A) and red (44B), and that of Moscato Ottonel being reddish (44b). The variety IASMA ECO 3 has no prostrate and erect hairs on the ribs and between the ribs, while the Malvasia di Candia variety has medium density creeping hairs between the ribs and on the ribs. Erect hairs are absent. In Muscat Ottonel variety there are no erect hairs on the ribs.

The mature leaf (UPOV 17) is small in the variety IASMA ECO 3, medium sized in Muscat Ottonel, and large in Malvasia di Candia. The color of the upper side is green (150 A) in Muscat Ottonel and dark green (134N) in Malvasia di Candia, and medium green (149A) in the variety IASMA ECO 3.

The goffering of blade and undulation of blade between main and lateral veins are absent in Malvasia di Candia variety and Muscat Ottonel variety, and weak in the variety IASMA ECO 3.

The variety IASMA ECO 3 teeth are convex; their size, in relation to blade size, is medium and the length of teeth is long compared to their width. Muscat Ottonel variety teeth are convex in both sides, their size in relation to blade size is short and the length of teeth compared with their width is short. In Malvasia di Candia variety teeth are rectilinear in both sides, and their size in relation to blade size is medium, the length of teeth compared with their width is medium.

The petiole sinus of the variety IASMA ECO 3 is slightly open and the shape of its base is V shaped, while in Muscat Ottonel variety is closed V shaped and in Malvasia di Candia variety is slightly open and U shaped.

The base of upper lateral sinuses is U shaped in the variety IASMA ECO 3, and brace shaped in Muscat Ottonel variety and V shaped in Malvasia di Candia variety.

The density of erect hairs on the veins of the lower side is high in the variety IASMA ECO 3, absent in Malvasia di Candia variety and medium in Muscat Ottonel variety. Erect hairs are present in Muscat Ottonel variety on the main veins of the upper side, in Malvasia di Candia variety and the variety IASMA ECO 3 are absent. The length of petiole, compared to that of middle vein, is slightly shorter in the variety IASMA ECO 3 and longer in Malvasia di Candia variety and equal in Muscat Ottonel variety.

The main color of woody shoot is reddish brown in Moscato Ottonel variety and brownish in Malvasia di Candia variety and in the variety IASMA ECO 3.

In the variety IASMA ECO 3, the first inflorescence stand on 2nd node, and has very high basal bud fertility, in Malvasia di Candia variety the insertion of the first inflorescence is at 3 and 4 node, and has medium fertility of the buds; Muscat Ottonel variety first inflorescence is at the third internode for and has 3 very low basal fertility. The number of inflorescences per shoot is 1.1 to 2 in parents, and 2.1 to 2.5 in the variety IASMA ECO 3. The first inflorescence of the variety IASMA ECO 3 is about 13 cm long, the date of full bloom is around 5th June, while in Muscat Ottonel variety the date of full bloom is 7th June, and its first inflorescence is 20 cm long.

Findings of Molecular Investigations

DNA was extracted from young leaves of different accessions for each variety by using the Doyle and Doyle extraction method (1990) as modified by Grando et al. (2003). Molecular markers were obtained by analyzing DNA specimens at the 9 microsatellite loci specified by the European projects named Gen-Res81 and Grape-Gen06 for vine variety characterisation and at locus VMC1B11 (Vitis Microsatellite Consortium). In particular, the primers and amplification conditions described by Thomas and Scott (1993) for locus VVS2, Bowers et al. (1996) for loci VVMD5 and VVMD7, Bowerset al. (1999) for loci VVMD25, VVMD27, VVMD28 and VVMD32 and Sefc et al. (1999) for loci VrZAG62 and VrZAG79 were applied. PCR products were separated and analyzed with the Genetic Analyzer ABI3130 and the GeneMapper® v4.0 software. The results are shown in Table 1 below.

Cultivation Characteristics and Suitability

The present invention vine variety shows good vigour with medium sprouting stage, with green-yellow, medium-sized, globose berry with medium thickness skin. The bunch is medium-sized, conical, relatively compact and often winged. It has a good yield and is relatively quite resistant to botrytis. Its physiological maturity occurs in the second stage; it shows a good capacity to accumulate sugars with low acidity values, especially in warm vintage years. It can perfectly stand winter cold and shows a good resistance to downy mildew and a medium resistance to powdery mildew. It prefers relatively fertile mixed hilly soils. It is ideal to produce delicate aromatic wines at altitudes exceeding 400 m above sea level or on slopes facing north.

Use

The present invention vine variety is particularly suited to produce fresh aromatic white wine; its taste recalls lemon balm and white peach with intense organoleptic characteristics; medium-low acidic strength (low in warm vintage years). It produces medium-body wines with good alcohol content and good sapidity, slightly aromatic and very peculiar. It can also be successfully used to produce still pure or mixed wines.
